Electromagnetic switch element with arcuate pole faces

Electromagnetic switching element, in particular a contactor, with a coil (14), a stationary yoke (9) and an armature (8), the switch contacts (16) carries and between a first switching position in which it is spaced from the yoke (9) and a second switching position in which it is in the immediate vicinity of the yoke (9), is movably held, and the switching contacts (16) of the armature (8) in these two switch positions with stationary switch contacts (15) cooperate to realize different switching states, wherein the armature (8) and the yoke (9) have facing surface portions (10, 11, 12, 13) which touch or touch in the second switching position. According to the invention, it is provided
